1、Introduction to JDL Series Mechanical Top Drive Core Drilling Rig
JDL series drilling rig is a mechanical top-drive water well drilling equipment which integrates mud drilling with air drilling. It solves the problems of difficult drilling by air DTH hammer in soil layer air drilling and low drilling efficiency in hard rock, gravel and pebble layer mud drilling. Mechanical top-drive drilling rig can adapt to various strata, and drilling efficiency is efficient and energy-saving.
2、Features of JDL Series Mechanical Top Drive Core Drilling Rig
2.1 The function integration of mud drilling and air drilling is realized.
2.2 Some functional interfaces are reserved in the hydraulic control system of drilling rig, which can be extended according to the technological requirements of different users.
2.3 The main spindle of the drilling rig adopts mechanical transmission, the transmission efficiency is doubled, and the power consumption is greatly reduced.
2.4 The drilling rig adopts mechanical top-drive power head and long stroke double speed mechanism to improve drilling efficiency and reduce drilling blockage and burning accidents.
2.5 The drilling rig adopts mechanical winch, which has fast lifting speed and is easy to handle
